Trump impeachment tracker: Following all the action in Congress

House Democrats have launched an impeachment inquiry against President Donald Trump. Their investigation is based on a whistleblower complaint from a US intelligence official about Trump’s efforts to pressure Ukraine to investigate his political rivals, including former Vice President Joe Biden, a leading 2020 candidate. There is no evidence of wrongdoing by Biden.

CNN is tracking the requests and subpoenas from House Democrats as they collect documents and testimony and move toward drafting articles of impeachment against Trump. If a majority of House lawmakers approve any of the articles, an impeachment trial will be held in the Senate.
